Eastern 7 years ago operated 3 daily southampton - Brussels flights. The first departed at about 0700am the next 2 1400 and 1730ish. This regular service meant that business people which Eastern attract rather than cheap tourists could do a days work and return the same day, avoiding expensive hotel stays.
This worked until Flybe began domestic domination by jumping on existing routes by other carriers and swamped the routes with oversize aircraft and services to get the competitor off the route at any cost, which has proved to be putting nails in their own coffin but thats another story.
Once the competitor was gone they then reduced the number of services back down to one daily at inconvenient times which the business man/woman did not like any they dissapeared to London and would also include expensive overnight Brussels accommodation if they flew from Southampton. The passengers left in droves and eventually Flybe pulled off the route. Eastern then try to resurrect the route but the only slot times available were the crappy mid morning/early afternoon which nobody wanted. Hence pull of route which was opearating quite nicely
I hope this explains thing clearly
